And if they had no intention to kill him they certainly aren't showing any regret and all the comments I've seen so far are actually bragging about his death and claiming that he deserved to die.
No, they aren't and they are certainly gloating about his death which goes to show how despicable they are and how dangerous their ideology is since they have shown themselves to be prepared to back up their words with actions. I'm just saying that based on the reporting on the assault it seems they didn't beat him up or intentionally hurt him that seriously - they just don't care it happened and think he deserved it anyway.
An update: the suspect is in police custody
after he gave himself up to them. The police has several eyewitnesses and there are no other suspects in the case. According to the police they had interviewed the victim in the hospital and he had told the police he had spat at the protesters when he passed by them. After the death of the victim the police had reclassified the crime being investigated to an aggravated manslaughter.
The reason there were no police around was that the police was given the notification about a planned public gathering late in the night - but within the six hour time limit the law requires - and the information given to the police was also misleading. According to the notification there would only be some people distributing leaflets with no mention of a protest or even who would be organizing the activity. It will be seen if there are consequences about giving a misleading notification to the police.
The fact that the suspect gave himself up to the police and there are no other suspects confirms my suspicion that despite the SVL using this in their propaganda this was just an individual member losing his self-control after getting spat at. Based on the previous cases the MO seems to be that when the organization supports a violent action there are several people involved in an organized strike and the suspects hide from the police at least for while. The violence is also more brutal than just shoving someone. Based on what I've read about them the organization has a high regard for discipline and I guess they didn't want to protect a member who didn't have an "official" approval for his violent action.
Edit2: Botched the abbreviation.
Yet another edit to give a picture about how organized the right-wing extremists are internationally: this discussion reminded me about an interview
(in Finnish) with Esa Henrik Holappa, one of the founders of SVL. He has quit the organization and nowadays tries to fix his past mistakes by telling his personal story and exposing his knowledge about the Neo-Nazis. He names Richard Scutari
as his mentor in Neo-Nazi ideology and he was also in regular correspondence with David Duke and few infamous European Neo-Nazis. SVL itself is a Finnish branch of a Nordic Neo-Nazi organization.
Still editing: According to new information
(Finnish again, sorry) the suspect is the same person who made the notification to the police. In his book the aforementioned former member Esa Holappa named this guy as being in charge of SVL activities in Helsinki. Previously I could understand how the police might not have paid much attention to some random people planning to spread leaflets but the notifier's identity should have and probably did rung figurative alarm bells in the police station. Yes, there was both an anti-immigration and an anti-racism demonstration going on elsewhere in the city and the police had to put resources to keep them separate but not paying attention to a known violent organization's planned activity elsewhere isn't excusable. There is a lone police van visible in the background on the video SVL published about the incident which suggests that the police was aware something might happen but didn't take it seriously enough and failed to prepare properly. A more visible police presence could probably have prevented the incident altogether.
Luckily there has been discussion about how the right-wing extremism should be taken more seriously and people are demanding legislative action. A few leftist bloggers have also pointed out that SVL is already violating several statutes of the law by for example explicitly promoting armed rebellion and there is no need to start limiting free speech in ways that might have unintended consequences. The officials just need to stop ignoring the danger and enforce the existing laws.
